NVIDIA Mellanox MCP1650-H001E30 QSFP56 Passive Copper Cable, 200Gb/s HDR, 1m, 30 AWG, LSZH: This is a 1-meter passive copper twinaxial cable (DAC) in QSFP56 form factor for 200Gb/s HDR InfiniBand and 200GbE Ethernet. The cable uses 30 AWG conductors with a Low Smoke Zero Halogen (LSZH) jacket. This is a passive direct-attach copper assembly with no active electronics, not an active copper or optical cable. This is a refurbished unit.
Engineering Context
The MCP1650-H001E30 uses PAM4 signaling at 50Gb/s per lane across 4 lanes to deliver 200Gb/s HDR. Passive copper at 1m provides the lowest-latency and lowest-power option for in-rack interconnects, with zero transceiver power draw on either end. The 30 AWG gauge is the standard for passive copper at HDR rates and 1m reach. The LSZH jacket complies with strict data center fire codes. The cable is designed to operate with FEC engaged on the host port.
Deployment & Use Cases
In-rack HDR InfiniBand connectivity between Quantum series switches and ConnectX-6 / ConnectX-7 HCAs. Top-of-Rack to host server links in HPC compute nodes. GPU-to-GPU fabric interconnects in NVIDIA DGX systems and HGX clusters. 200GbE Ethernet ToR connectivity in NVIDIA Spectrum-2 / Spectrum-3 deployments.
